The purpose of this directive is to provide guidance on selecting a presumptive remedy or combination of presumptive remedies for wood treater sites with soils, sediments, and sludges that are contaminated primarily with creosote, pentachlorophenol, and/or chromated copper arsenate. This guidance describes the contaminants generally found at wood treater sites; presents the presumptive remedies for contaminated soils, sediments, and sludges at wood treater sites; describes the presumptive remedy process concerning the site characterization and technology screening steps; and outlines the data that should be used to select a presumptive remedy. This directive is designed to assist Superfund site managers (i.e., Remedial Project Managers (RPMs) and On-Scene Coordinators (OSCs)) in selecting remedies for wood treater sites. To ensure a full understanding of wood treater site characterization and remedy selection, site managers should refer to the FS/ROD analysis, which is summarized in Appendix A of this document, and the documents cited as references at the end of this document. |
